51. A one piece molded needle hub assembly to be used with the molded needle holder of claim 48, comprising: a proximal section and a distal section, said proximal section dimensioned to fit to the aperture of the neck of said holder, a double ended needle extending through said distal and proximal sections, a pair of catches formed at opposite sides of the outer circumference of said proximal section, and a through slot formed in said proximal section behind each of said catches to enable flexible movements of said catch transversely to said proximal section.
52. A method of manufacturing a needle holder, comprising the steps of:
a) forming a cylindrical body having an opening at one end through which a fluid storage tube is insertable into the cavity of said body;

b) forming a neck integral to said body having an aperture smaller in diameter than said opening of said body;
c) forming at least one orifice transverse to a side of said neck for accepting a catch from a needle hub to be inserted into said neck;
d) extending an elongate needle cover integrally front said neck; and e) coupling a finger grasp means to said needle cover.
53. Method of claim 52, wherein said finger grasp means comprises a wing nut, said method further comprising the step of:
notching or thinning the junction where said needle cover is integrally extended from said neck so that a given torque applied to said wing nut relative to ether said neck or said body will separate said needle cover from said neck.
54. A method of manufacturing a needle holder, comprising the steps of:
a) forming a cylindrical body having an opening at one end through which a fluid storage tube is insertable into the cavity of said body;
b) forming a neck integral to said body having an aperture smaller in diameter than said opening of said body;
c) forming one lock mechanism transverse to a side of said neck;
d) extending an elongate needle cover integrally from said neck;
e) coupling a finger grasp means to said needle cover;
f) forming a needle hub assembly about a double ended needle with one end of said needle extending from its distal end and an other end of said needle extending from its proximal end;
g) forming an other lock mechanism at said needle hub assembly;
h) inserting said needle hub to the cavity of said body through said opening of said body; and I) press fitting said needle hub to said aperture of said neck until said one and other lock mechanisms coast to fixedly hold said needle hub to said neck with said one needle end extending from said needle hub into said needle cover and said other needle end extending from said needle hub into the cavity of said body where said fluid storage tube is to be inserted.
55. Method of claim 54, wherein said finger grasp means comprises a wing nut, said method further comprising the step of:
notching or thinning the junction where said needle cover is integrally joined to said neck so that a torque of less than approximately 60 ounce inches or greater applied to said wing nut relative to either said neck or said body will separate said needle cover from said neck.
56. Method of claim 54, wherein said step c comprises the step of forming a pair of orifices at opposite sides of said neck, and wherein said step g comprises the step of forming a pair of catches at opposite sides of said needle hub;
wherein said step a further comprises the step of press fitting said needle hub into said aperture of said neck until said catches each latch onto a corresponding one of said orifices to fixedly retain said needle hub to said neck.
57. Method of claim 54, wherein said step a comprises integrally forming said finger grasp means and said cover, said finger grasp means being a wing nut.
